- Need to provide absolute URL path.
- Has an overhead of extra remote trip.
- but has the advantage of being able to refer to any resource on the same or different domain
- also allows book marking of the page.
forward
- Forward action takes place within the server without the knowledge of the browser.
- No extra network trip.
